Mrz, here is something to try that can't hurt I don't think. See if YOU can pack the wound with plain granulated sugar. Cover both sides. Irrigate/flush if you can every day and re pack.

Honest, sugar is what is used for those nasty spider bites that rot out and leave holes. It is what the Dr told my mom to use when she was bitten by a brown recluse/fiddle back.

Now, if you can't irrigate it, I wouldn't reccomend trying this. God knows what rotten sugar might do, but you could ask your Dr? It might just melt away.....
